Cisco Designing and Implementing Enterprise Network Assurance Sample Questions (Q84-Q89):

NEW QUESTION # 84
Drag and Drop Question
Drag and drop the commands from the bottom onto the boxes in the configuration to modify the DNS servers on an Enterprise Agent running on a Cisco Catalyst 9300 Switch.

Answer:

Explanation:

Explanation:
Modifying DNS settings for an Enterprise Agent running in App-Hosting on a Catalyst 9300 requires shutting down the running container before applying changes and then restarting it.
- deactivate removes the running application from service.
- stop halts the container so configuration changes (such as new DNS servers) can be applied.
- start brings the container back up after the configuration update.
- activate enables the application, allowing the Enterprise Agent to resume operation with the updated DNS configuration.


NEW QUESTION # 85
A company is noticing sporadic slowdowns in their web application performance, impacting user experience. They suspect it might be related to high CPU utilization on employee laptops, potentially caused by background processes. Which ThousandEyes alert type and condition combination would be most effective in identifying if endpoint CPU performance is contributing to this issue?

Answer: D

Explanation:
In the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum, isolating performance issues on end-user machines requires a combination of application-layer experience data and local system telemetry. When an architect suspects that local hardware constraints, such as high CPU usage, are degrading the digital experience, the Endpoint Agent is the required vantage point.
The correct combination is Real User Tests > Endpoint, CPU utilization ≥ % (Option C). This alert configuration is effective for several reasons:
Targeted Visibility: It directly monitors the user's device (Endpoint) where the hardware bottleneck is suspected to reside.
Real-Time Context: By utilizing Real User Tests (RUM), the agent gathers performance data during actual user activity (e.g., browsing the web application). This ensures that the CPU spikes are correlated with active application usage, providing a representative view of the impact on experience.
Threshold Alerting: The condition monitors for CPU utilization exceeding a defined percentage threshold ( %). This allows IT teams to be notified only when the CPU load reaches problematic levels that are known to cause application sluggishness or browser "freezing".


NEW QUESTION # 86
A network engineer deploys a ThousandEyes Docker agent on a switch using app-hosting. The agent needs to communicate through a proxy server, but this configuration was missed during the initial deployment. The engineer adds the proxy settings to the app-hosting configuration. What is the next step to ensure the agent uses the proxy and appears online in the ThousandEyes portal?

Answer: B


NEW QUESTION # 87
Refer to the exhibit. A customer is deploying a Cisco ThousandEyes Enterprise Agent on a Cisco Catalyst 9300 Series Switch, but the Docker container is not running. Which command enables the Docker container on the switch to proceed with the Enterprise Agent installation?

Answer: A

Explanation:
The show iox-service output shows all IOx services - including Docker - are Not Running.
On Catalyst 9300 switches, IOx (the application hosting environment) must be enabled globally with the iox command before Docker containers, including the ThousandEyes Enterprise Agent, can run.


NEW QUESTION # 88
You're analyzing NetFlow data for a network supporting voice and video traffic. The data shows consistent spikes in delay and jitter during peak hours. Which optimization would you recommend?

Answer: C

Explanation:
In the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) curriculum, capacity planning and optimization are driven by telemetry data such as NetFlow. When NetFlow identifies that delay and jitter--metrics highly impactful to real-time traffic--spike during peak hours, it indicates that high-priority packets are competing for resources with bulk data.
The most appropriate recommendation is to tune the existing QoS configuration (Option C). This involves adjusting the Queuing and Scheduling policies on the routers to ensure that voice and video traffic (typically marked with EF and AF41/AF42 DSCP values) is serviced before other traffic classes during periods of congestion. This solution is targeted, cost-effective, and directly addresses the observed jitter issues without the need for massive capital expenditure.
